the towns of the Lower St. Lawrence, in northern Aroostook Co., 
Maine, and Madawaska Co., New Brunswick; and the past summer 
was found by the writers along the Canadian Pacific Railway at Ft. 
Fairfield, Maine, and at Aroostook Junction, New Brunswick, also on 
the Washington County Railroad at Pembroke, Maine; and recently 
it has been collected by Messrs. Walter Deane and Edward L. Rand 
in dry soil in Swansea, Massachusetts. In the 7th edition of Gray’s 
Manual a somewhat similar plant was included by Hitchcock under 
var. breviseta (Déll.) Hitchc., based upon Dóll's Panicum viride 8 
brevisetum with * Aehrchen kaum ein wenig von den Hiillborsten 
überragt."' The latter plant, true var. brevisetum, was collected in 
1884 by Dr. C. W. Swan on dumps at Lowell, Mass., Dr. Swan’s 
material having the bristles only 3-4 mm. long, i. e. scarcely or only 
slightly exceeding the spikelets, and a similar plant occurs about 
Boundary Lake in northern Maine and adjacent Quebec. ‘The com- 
moner slender-spiked and narrow-leaved depressed plant of eastern 
and northern Maine and eastern Canada, however, has its bristles 
(4-6 mm. long) conspicuously longer than the spikelets and is very 
satisfactorily matched by material distributed by Degen & Flatt in 
the Gramina Hungarica (No. 4) as Setaria viridis, var. Weinmanni. 
It is noteworthy that in the American material as well as in the 
Hungarian specimens the purplish color of the bristles (a character 
emphasized by recent European authors) is developed only in a few 
of the most mature spikes. Roemer & Schultes? in their original 
description of the plant as Setaria Weinmanni do not mention the 
color of the bristles but state that their plant is intermediate between 
S. glauca and S. viridis, though Koch ? in his Synopsis treats it as a 
small purplish form of S. viridis: “minor saepe colore sordide pur- 
pureo suffusa," and many subsequent authors have emphasized the 
purple bristles. From a study of the material at hand, however, it 
would seem that the purple color is a less significant character of the 
plant than its habit, narrow leaves, and slender spikes. 
ZIZANIA AQUATICA L. This narrow-leaved plant abounds in the 
lower waters of the Nerepis River at Westfield, New Brunswick. 
Although formerly reported from New Brunswick a new record is 
desirable in view of the recent re-segregation of Zizania.
